Wheat breeding approaches for designing wheat to thrive in a warmer world

PLANTS, PEOPLE, PLANET, EarlyView.
Wheat is a vital food crop, accounting for approximately 20% of daily calories and protein consumed worldwide. However, modern‐day wheat is under pressure from global change. The improvement rate of wheat yields is not keeping up with the demand of our growing population. Furthermore, abiotic and biotic stressors are becoming more prevalent. This paper

The use of metabolomic profiling to evaluate Aegilops tauschii Coss accessions of various geographical origin from the VIR collection

Труды по прикладной ботанике, генетике и селекции
Background. Aegilops tauschii Coss. is a diploid cereal species carrying the D genome of polyploid wheat, which determines the baking properties of bread wheat. A. tauschii is often used to improve old cultivars of Triticum aestivum L.

Development and Utilization of Introgression Lines Using Synthetic Octaploid Wheat (Aegilops tauschii × Hexaploid Wheat) as Donor

Frontiers in Plant Science, 2018
As the diploid progenitor of common wheat, Aegilops tauschii Cosson (DD, 2n = 2x = 14) is considered to be a promising genetic resource for the improvement of common wheat. In this work, we demonstrated that the efficiency of transferring A.

Climate-Change-Driven Shifts in Aegilops tauschii Species Distribution: Implications for Food Security and Ecological Conservation

Diversity
Climate change has diverse effects on the planet’s environment, including changes and shifts in the distribution and abundance of species. In this paper, we present a robust prediction ensemble algorithm for the current and future species distribution of

Natural Variation in TaFAD8‐D Promoter Enhances Thermotolerance in Wheat Through Fatty Acid and Lipid Remodelling

Plant Biotechnology Journal, EarlyView.
ABSTRACT Heat stress (HS) has become an increasing threat to wheat productivity under global warming. However, the genetic loci for thermotolerance and the underlying molecular mechanisms remain largely unknown. In this study, genetic mapping identified a thermotolerance locus, QMpe.cau‐2D, encoding fatty acid desaturase 8 (FAD8), with the transposable

Allele mining of TaGRF-2D gene 5'-UTR in Triticum aestivum and Aegilops tauschii genotypes.

PLoS ONE, 2020
The low diversity of the D-subgenome of bread wheat requires the involvement of new alleles for breeding. In grasses, the allelic state of Growth Regulating Factor (GRF) gene is correlated with nitrogen uptake.

The Evolution and Origin of Allotetraploid Aegilops geniculata Revealed by the Homoeolog‐Resolved Genome Assembly

Plant Biotechnology Journal, EarlyView.
ABSTRACT Aegilops geniculata Roth is a tetraploid (MgMgUgUg; 2n = 4x = 28) wild relative of wheat and a valuable source of genetic diversity for improving agronomic traits. We present a high‐quality homoeolog‐resolved assembly and annotation of the Ae.

An ancestral NB-LRR with duplicated 3′UTRs confers stripe rust resistance in wheat and barley

Nature Communications, 2019
Stripe rust is a serious threat to wheat production. Here, the authors reveal that the resistance gene, only present in the wheat progenitor Aegilops tauschii and its derived synthetic wheat, encodes a nucleotide oligomerization domain-like receptor and ...

The TaMADS2‐TaTBL21 Module Enhances Wheat Resistance to Stripe Rust by Activating TaGKL‐Mediated Immunity

Plant Biotechnology Journal, EarlyView.
ABSTRACT Wheat stripe rust (Puccinia striiformis f. sp. tritici, Pst) poses a catastrophic threat to global food security. While MADS‐box transcription factors regulate development and abiotic stress, their roles in plant‐pathogen immunity remain enigmatic.
